1) Is the tungsten worth it, does the extra weight really turn into more
fish hooked? *for YOU

I primarily use them in high water to get flies down without extra
bulk.

2) How the hell do you tell, a year or more later, looking into your boxes
which flies are tungsten, which regular bead

Thread color. Weighted flies that have lead or tungsten vice regular
beadheads, I tie with a red thread head, or in the case of the
beadheads, red behind the bead.
